  • SX50. Sound Comes First 

    SX50 are a pair of compact hi-fi speakers designed to sit in confined spaces like bookshelves – hence the name. Despite their modest size, they output a confident, detailed, and rich stereo sound to fill smaller rooms with music as it was meant to be heard.  It’s the combination of engineering quality and value, that make SX50 so hard to beat.

    Rock Solid Foundations

    Hi-fi speaker engineering starts with the cabinet. Computer-aided design (CAD) was used extensively to refine SX50’s internal structures to ensure that while the drivers are vibrating with your music, the cabinet isn’t. This means that every millimetre of movement from the drivers is directed where it should be – at you.

    Sound Reproduction

    SX50 speakers have a 135mm (5.25”) woofer made from treated paper. Hi-fi manufacturers have used it for years, as paper’s impressive strength-to-weight ratio is matched by excellent tonality – so music sounds rich, well defined, and real. 25mm (1”) soft dome tweeters, made from treated silk, take care of the higher frequencies – with the same balance of realism and refinement.

    SX50 Driver Detail

    Two Drivers, One Voice

    Our team in London took great care and attention when designing the crossovers in SX50 – as they’re responsible for ensuring that each driver receives the correct frequency. Accuracy of timing and stereo imaging depend on phase remaining completely linear, from top to bottom. The result? Your music sounds engaging, energetic and real.

    Engineered, Front to Back

    Spin SX50 around to see that our attention-to-detail runs from front to back. There’s a neat bass reflex port that lets you fine-tune lower frequencies, by adjusting the position of the speaker with the wall. Immediately below are a pair of high-quality speaker binding posts (connectors), which can accept thick cable – with or without banana plugs.

    Designed for Real Life

    New look SX50’s clean, understated design allows them to sit in a variety of spaces, and work well in all. Leave the grilles on to protect the drivers from little fingers, or to help blend in with your books. Alternatively, take them off to celebrate your great taste in music (and speakers).
